Summary: In a 42-day microcosm experiment, we found that nanoplastics have significant effects on soil microbial community structure, nitrogen removal processes, greenhouse gas emissions, and ecosystem multifunctionality. Positively charged nanoplastics have a stronger impact on soil microbial community structure and functions. Nanoplastics at environmentally realistic concentration inhibit soil denitrification but enhance anammox. Nanoplastics decrease soil N2O flux, while increasing CO2 and CH4 emissions. Nanoplastics can increase ecosystem multifunctionality but also increase greenhouse gas emissions.

Summary: Wheat is a crucial crop for global food security, however, boosting wheat yield on current cropping areas may not be enough to meet future global food demands. Climate warming has allowed wheat to be cultivated in previously uncultivated areas at higher latitudes. However, growing wheat in these regions presents several challenges, including the release of greenhouse gases. It is crucial to conduct research and develop wheat production techniques that minimize environmental damage in high latitude areas.

Summary: The study investigated the effect of different grazing intensities on nitrous oxide emissions in alpine meadows on the Zoige Plateau. Results showed that grazing activities can influence N2O emissions, but the relationship between grazing intensity and N2O emissions is not always significant. Soil N2O emission rates were correlated with factors such as soil water-filled pore space and available phosphorus, highlighting the importance of proper grazing intensity in reducing N2O emissions.

Summary: A mathematical model with time-varying parameters is proposed to describe the potential effects of rapid global warming on marine ecosystems. The study indicates that global warming is leading marine ecosystems to an imbalanced state by significantly reducing marine plankton and fishery resources. If the trend continues, it could damage marine ecosystems, especially fishery resources, in the long run.

Summary: This study investigated the differences in anaerobic soil organic carbon (SOC) mineralization following permafrost thaw in peatlands and the vulnerability of previously-frozen peat. The research found that the rate of SOC mineralization decreased with depth and peat age, but there were no significant differences in mineralization rates between recently-thawed peat and peat thawed 200 years ago. The study suggests that rapid SOC loss following thaw is unlikely.

Summary: This study simulated the N2O emissions in different regions of the Qinghai-Tibetan Plateau using the TRIPLEX-GHG model and predicted its future trend. The results showed that the total natural N2O emissions slightly increased from 1970 to 2017, with the most significant increase in the northern and southeastern regions. Temperature was found to be the dominant factor for N2O emissions in high-altitude regions. It is projected that the natural N2O emissions of the Qinghai-Tibetan Plateau will continue to increase if the climate becomes warmer and wetter.

Summary: The combination of biochar and fertilizer has the potential to improve environmental quality and agricultural productivity. This study found that biochar and inorganic fertilizer had different effects on soil, with higher fertilizer application rates increasing bacterial gene abundance and nitrification and denitrification potential, while not affecting fungal genes. On the other hand, increased biochar application rates increased fungal activities but decreased bacterial genes and nitrification and denitrification potential, especially in the rhizosphere. Structural equation modeling showed that bacteria had a greater contribution to total denitrification than fungi in the non-rhizosphere, but the opposite trend was observed in the rhizosphere. These findings suggest that partially substituting inorganic fertilizers with biochar can reduce potential N2O production from bacterial nitrification and denitrification.

Summary: Alpine wetlands play an important role in the global carbon balance, but are experiencing severe degradation under climate change and human activities. This study investigated the effect of wetland degradation on carbon fluxes and found that carbon sequestration capacity decreased with intensification of the degradation. The degradation also led to reduced soil water content, soil organic carbon, and microbial biomass. These findings highlight the importance of managing and utilizing degraded wetlands in response to climate change.
